Crop Video Online

Crop unwanted edges, reframe a recording, or prepare a video for social media without sending the source file to a server. The visual crop frame shows exactly which area will remain in the exported video. Drag the frame to reposition it, resize it from the corner, or enter exact X, Y, width, and height values when precision matters.

Crop for landscape, portrait, and square layouts

Use the built-in aspect ratio presets to switch quickly between common destinations. The 16:9 preset works well for widescreen presentations and standard video players. Choose 9:16 for vertical short-form video, 1:1 for a square post, or 4:5 for a taller feed layout. Select Free when you need a custom frame that does not follow a fixed ratio.

The crop is centered whenever you choose a preset, so you begin with a balanced composition. You can then drag the selected region to keep the most important subject in frame. The pixel controls update with the visual selection and remain available for fine adjustments.

Private browser-based video cropping

Processing happens locally with FFmpeg compiled to WebAssembly. The file stays on your device throughout the workflow, and the finished MP4 is created as a temporary browser download. This makes the tool useful for personal footage, draft creative work, and other files you would rather not upload to an unknown service.

The export uses H.264 video and AAC audio for broad playback support. Crop coordinates and dimensions are normalized to even pixels to avoid compatibility problems with common H.264 encoders. For large or long videos, keep this tab open while processing; browser-based conversion can take longer than a native desktop editor because it is limited by the memory and CPU available to the browser.

After processing finishes, preview the result and download it immediately. If the framing is not right, adjust the crop area and run the tool again—the original file remains unchanged.
